Ending looks like super unfinished, especially after you realize it's the 30 years old series end lol
Honestly problem is not just is no ending, it's a lot after act 2, newspaper no reaction on player, no armor for Sylune Shadowheart choice, she swap hairs color but still have Shar accessory, and etc. I truly support your game and buys 10x copies, I playing solo runs on early access, but it's really looks unfinished, that's not what 30 years old series ends looks like
Considering how they treat Sarevok and Viconia in this let's say this is a fanfic of the original trilogy and not actual continuation.
Neither of those things are up to Larian. 5e lore says these outcomes better, larian actually fixed them. They are both in amazingly better condition than the 5e cannon says they should be.
from reddit: (apologies for tone and wording but while the bias is reddits this is accurate to the book and its the clearest summary I know of online.)
Minsc and Boo's Journal of Villany
Wizards of the Coast just released a 5e supplement written by James Ohlen called Minsc and Boo's Journal of Villainy. Alongside being a fantastic 5e source it updates a lot of classic Baldur's Gate characters to the fifth edition. Here's some of the things we learn about what our old friends have been up to:
Valygar and Xan both work for Candlekeep. Valygar has taken potions of longevity to continue his hunt for evil wizards. Xan, who is a "Blessed of Corellon," meaning his gender changes sometimes throughout his life, hopes to find a worthy heir for his moonblade before journeying to Evermeet.
Kivan and Faldorn are both members of the Emerald Enclave. Kivan is now married to Cernd and is attempting to expose Faldorn as an evil Shadow Druid.
Jaheira continues to serve the Harpers.
Minsc and Boo were petrified and spent nearly a century as a statue in Waterdeep before being freed. They are now members of an order known as the Knights of Bahamut.
Irenicus and Bodhi were placed in the Domains of Dread by the Dark Powers of Ravenloft. They now exist in a dark mirror of Suldanessellar. Irenicus is now a lich.
Montaran and Xzar have also returned from death and are members of the Shadow Thieves. Xzar has become a demilich which Montaran keeps in a bag of holding. There's also an insane simulacrum of Xzar running around.
Imoen also is a member of the Shadow Thieves. She was transformed into a vampire by Bodhi but has retained her good alignment.
Edwin now has the longevity of an elf, thanks to the Nether Scrolls. He is once more in good relationship with Thay and has taken over Razamith's Tower in Baldur's Gate.
Kagain is now a worshiper of Bhaal and leads an unscrupulous band of mercenaries in Baldur's Gate.
Saemon Havarion sold his soul to Baalzebul in exchange for long-life and fortune and is now desperately looking for a way out of the deal.
Sarevok became a homeless drug addict in Baldur's Gate until Bhaal, reborn, found him and made him a high priest of his clergy.
Viconia has started working with the cults of Elemental Evil to further the will of Shar.
EDIT: For those of you who are Neverwinter Nights fans, it also includes Aribeth de Tylmarande who is now a herald of Mephistopheles.
Given this is the CANON, that they made Viconia, the leader of Shar's temple and have a very strong, established and successful powerbase, is an incredible improvement on, she's still a low level cleric of Shar sent on adventuring missions. (I'm actually 100% happy with Viconia in BG3, she's exactly where I'd hope she'd be. Powerful, safe, no longer hunted and leading an established, reputable temple of her Goddess.)
Sarevok being the leader of a cult, secretly running aspects of the city and having a family, while still a betrayal of his redemption in ToB it's 100x better than 5e canon that he's a homeless bhaal cultist high on drugs
Given what Larian had to work with, they polished it into gold. The only question is why didn't we have to fight off Kagain in the undercity? and why wasn't Edwin in the game as from canon he's immortal and in BG city.
